I In Great Britain November 8, 194B According to the invention a heating unit or radiator comprises a casing, a heating element disposed centrally of said casing and capable of being heated to a high temperature, the said heating element being formed in or carried by components of greater area than the heating element and of high heat conductivity and connected at their outer ends or edges to the outer casing which is heat insulated from the central heating element for the purpose of enabling the concentrated central heat source at high temperature to heat a larger area uniformly at a lower temperature.

According to one form of the invention the said heating element is an electrical one and according to another form of the invention the heating element is constituted by a chimney or flue through which combustion gases ascend from a liquid fuel burner. v 1 v Reference will now be made to the accompanydrawings which illustrate constructions according to the invention and in which- Fig. l is a front elevation of an electrically heated radiator,

Fig. 2 is a sectional plan taken on the line X-X of Fig. 1,

Fig. 3 is an end elevation of the radiator'shown in Fig. 1,

Fig. 5 is a sectional plan taken on the Y-Y of Fig. 4,

,Fig. 6 is an end elevation of the radiator shown in Fig. 4, and

Fig. 7 is an elevation of a constructional detail of the radiator shown in Figs. 4 to 6.

Referring first to Figs. 1 to 3, the radiator comprises an outer casing l of sheet metal whose sides are formed with corrugations Zexcept for the centralportions which are formed to provide a chamber 3 extending throughout the height of the radiator. In the centre of the chamber line 3' is disposed an electrical heating element 4 supported between two sheets 5 of metal of high heat conductivity such as aluminium or copper. These metalsheets have central portions 6 which lie close together to form supports forthe heating element 4 which is secured in position between them by screws and nuts 1, plates 8 of heat insulating material being mounted externally 'of the portions 6 of the metal sheets coincident with the heating element. At the ends of the radiator the metal sheets 5 are spaced more widely apart than at the centre as shown in the sectional plan, Fig. 2. The metal sheets 5 are brought into abutting relationship at 9 near their outer ends where they pass through a slot formed between adjacent sections of the end wall ll] of the outer casing l. The extreme outer ends of the sheets 5 are bent at right angles in opposite directions" to iorm flanges l l which overlap similar flanges 23 formed on the vertical edges of the two components which form the end wall WI The joint: at each end of the radiator is completed to hold its; component portions together by sheet metal members 12 of flattened tubular form with slots in their inner wallswhich form on each member 12 two inwardly directed portions [3.
